$A \rightarrow B$ is an adiabatic process. If the total heat absorbed in the entire process ( $A \rightarrow B$ and $B \rightarrow C$ ) is $R T_2 \ln 10$, the value of $2 \log V_3$ is . . . . . [Use, molar heat capacity of the gas at constant pressure, $\mathrm{C}_{\mathrm{p}, \mathrm{m}}=\frac{5}{2} \mathrm{R}$ ]
